*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Van Vliet Lake in Wisconsin experiences the same seasonal temperature patterns typical of small inland lakes in the region. During winter the surface usually approaches freezing, about 32°F (0°C), and the lake often develops ice cover. In spring surface temperatures rise from roughly 34–55°F (1–13°C) as runoff and warming air raise the water. Peak summer surface temperatures commonly range from about 68–76°F (20–24°C), though shallow bays can briefly reach the upper 70s°F (25–26°C) on hot, calm days. By autumn the lake cools again to roughly 45–60°F (7–16°C). Deeper water remains considerably colder year-round, and actual temperatures vary with recent weather, wind, depth and shade.
Swimming is generally permitted at lakeside access points in Wisconsin, and Van Vliet Lake is used for recreational swimming when conditions are suitable. Whether swimming is advisable depends on water temperature, safety infrastructure and any local advisories: cold spring or late‑fall water increases the risk of cold shock and hypothermia, while winter ice cover makes open‑water swimming dangerous except for organized, supervised ice swims. Local health or conservation authorities may close areas temporarily for poor water quality, such as harmful algal blooms, so checking posted signs or local guidance before entering the water is wise.
